Do you have kids, and if so, what age are they?
Excellent question.
However I'd have to say Kirkwood does not have children. He actually thinks that the daughter wrote "a very thoughtful and well-constructed personal letter."
All she did in that letter was throw a verbal tantrum--complain about chores, and demanded to get paid for what is her normal duty as a member of a family. She decided that any job taking care of the house belonged to "the cleaning lady" or someone else, and she shouldn't be bothered with it.
If that had been written by one of my children, they wouldn't get off so lightly.
